Abstract: A shielding device for shielding a clearance between a frame member having an opening and a tube member received in the opening and movable substantially in the direction of an optical axis. The shielding device comprises an annular shielding member arranged between the inner circumference of the opening of the frame member and the outer circumference of the tube member. The annular shielding member is so slidably fitted on the tube member that its inner circumference may contact with the outer circumference portion of the tube member, and is either given substantially the same color as that of the outer circumference surface of the tube member or made substantially transparent at least at its portion having contact with the tube member.

Abstract: The voltage of batteries is detected, and a determination is made whether the detected voltage is less than the normal value. If the detected voltage is below the normal value, a determination is made whether a sound recording priority flag is on. If the sound recording priority mode has not been set, a low battery level warning sound is generated to indicate that the level of the battery is low. If a determination is made that the sound recording priority mode has been set, however, the battery level warning sound (or other various operating sounds of the camera) is not generated. As a result, noise is reduced because the battery level warning sound and/or other operating sounds are not recorded.

Abstract translation: 检测电池的电压，并且确定检测到的电压是否小于正常值。 如果检测到的电压低于正常值，则确定声音记录优先级标志是否打开。 如果没有设置录音优先模式，则会产生低电量警告声，以指示电池电量低。 然而，如果确定已经设置了声音记录优先模式，则不会产生电池电平警告声音（或照相机的其它各种操作声音）。 结果，由于没有记录电池电平警告声和/或其他操作声音，所以噪音降低。

Abstract: A lens barrel comprises a first cylindrical member having an inner peripheral surface, and a second cylindrical member internally fitted to the first cylindrical member and having an outer peripheral surface that facing in a radial direction to the inner peripheral surface. One of the inner peripheral surface and the outer peripheral surface is formed with first and second helical grooves extending in an axial direction in parallel with each other, and a third groove extending in only a circumferential direction continuously from one side ends of the first and second grooves. The other of the inner peripheral surface and the outer peripheral surface are formed with first and second protruded portions engaging respectively with the first and second grooves in alignment in the circumferential direction and enabling relative rotations between the first and second cylindrical members and relative movements in the axial direction therebetween. The first and second protruded portions engage respectively with the first and second grooves with the result that the fist and second cylindrical members make the relative rotations and the relative movements in the axial direction, and, when reaching the third groove, move through within the third groove, and the first and second cylindrical members are allowed to make only the relative rotations without moving in the axial direction. The third groove includes a guide portion, formed in continuation from the first groove, for guiding the first protruded portion into the first groove.
